ELECTRICAL FIRE ALARM AND EXTINGUISHING SYSTEM.

SPECIFICATION forming part of Letters Patent No. 443,724, dated December30, 1890.

Application filed April 12 1890. Serial No. 347,580. (No model.)

T 0 aZZ whom it may concern.-

Be it known that 1, CHARLES E. ONGLEY, a citizen of the United States,residing at New York city, in the county and State of New York,'haveinvented a new and useful Improvement in Electrical Fire Alarm andExtinguishing Systems, (Case R) of which the following is aspecification.

My invention relates, especially, to systems in which thermostaticcircuit-controllers are placed at suitable points in a structure to beprotected, and the circuit from such controllers is led to the office orother suitable point, at which is placed a transmitter adapted to bereleased upon the operation of the thermostat and to automaticallyrecord or signal the number of the thermostat or station at which thethermostat is placed and in which automatic sprinklers are provided forextinguishing the fire by the fusing of a part of the sprinkler, whichnormally holds the out lets closed.

My object is to provide a signalor alarm to indicate an accidentalbreaking or disarrangement of the automatic sprinkler and to so arrangethe circuits and apparatus that if the sprinkler gives way before thethermostatic circuit-controller operates a valve in the water-pipe shallbe closed, while if the thermostatic circuit-controller first operatessaid valve cannot be closed bythe automatic operation of the system.

A further object is to so arrange the apparatus that no confusion orinterference shall arise between a fire-alarm signal and a signal due toa disarrangement of the sprinkler.

My invention consists in the system and apparatus hereinafter describedfor accomplishing the above objects and in the several de-' tails ofconstruction, as will be hereinafter fully set forth.

In the accompanying drawiugs,which illustrate my invention, Figure 1 isa diagrammatic view of a system embodying my invention; and Fig. 2 is aplan view of two individual signal-transmitters-that is, transmittersadapted to send a certain number or arrangement of electrical impulsesto indicate the number of a station-mounted on a common base.

Refer-ring first to Fig. 1, 1 is a. water-pipe conducting water under asuitable pressure to the part of the building to be protected. At theend of the pipe or at intervals along the length of the pipe arearranged automatic sprinklers. A single sprinkler 2 is shown, althoughit will be understood that in practice several may be used with aseparate circuit for each sprinkler and relay-magnet or with a singlecircuit passingin series through a number of sprinklers, so that whenany one gives way the circuit will be opened. The sprinklerillustratedconsists of a cap 3, placed over the end of the tube and held in placeby the pivoted levers at, having inwardly-proj ecting shoulders underthe cap and normally held together by the fusible link 5. A conductingball, wedge, or other device 6 is placed between the projecting ends ofthe two levers 4 4:, and to piece 6 is connected one end of a circuitfrom a suitable battery, preferably a gravity-battery 7 The otherterminal of the battery is connected to the water-pipe. A relay-magnet Sis interposed in this circuit and the armature thereof is normallyattracted. If by accident or otherwise 6 is disarranged or falls awayfrom it-sseat, as it would do should levers at 4 separate or if theyshould move away from each other slightly, this circuit will bebroken,the effect being to allow the relay-armature to fall back againstcontact 9 and close a second circuit, which is indicated on the drawingsby the single arrow-heads, and may be traced as follows: from thebattery 10 to the annunciator or electromagnetic circuit-closer 11, tothe releasing-magnet 12 of the signal-transmitter X at the right, to theframe of the clock-work at the left, thence to the revolving arm 13', tocontact-spring 14, against which the arm normally bears, to contact 9,and through the armature to the other pole of the battery. This circuitenergizes magnet 12 and releases the clock-work at the right. Analarm-bell 25 may be placed in this circuit, if desirable. Referring nowto Fig. 2, the mechanism there shown, which may be called a duplexindividual signal-transmitter, will be describ ed. The apparatusillustrated is intended for use at a station whose number is 4, as in-IOC dicated by the four eircuit-n'iaking teeth on the wheels 15 15. Inthe position shown the clock-work or motors (indicated by the wheels 1616) are wound up, and the devices are in condition to run down whenreleased. In this position the revolvingarms 1f} 13 bear against thecontact springs ll 11'. The contactsprings 17 17 are adjacent to but outof contact with the wheels 15 15' 17, being conzo neeted to wire 17. Thesprings 18 18' are over but out of contact with said wheels. From saidwheels project pins lit, which as the wheels revolve come in contactwith springs18 18. At the termination of, preferi5 ably, two revolutionsof wheel 15 the arm 13' comes to rest against contact-spring 20. On thetransmitter Y at the left is an additional spring 21 between 14: and 20,which 13 touches as it revolves. At this transmitter,

20 also, is a con tact-spring 22, which bears against 1.3 when set foroperation. The magnet 12 and its armature control the detent orescapement 23 of the right signal-transit)itter. The magnet 12 and itsarmature control the de- 25 tent or escapement 23' of the lefttransmitter.

Referring again to Fig. 1, H are thermostatic circuitcontrollers placedin the apartment to be protected, preferably adjacent to the sprinklers.These cireuitcontrollers, of which any number maybe used, are adjustedto close or change the circuit at a temperature considerably lower thanthat required to re lease the automaticsprinklers. From one side of eachthermostatic circuit-controller a wire extends to the battery 10. Fromthe other side of the thermostata wire extends to magnet- ]2, spring 14,arm 13, through the frame of the apparatus, to wire 26, and to the otherpole of the battery. 'hen, therefore, the heat 40 is sufficient tooperate the thermostat, the

above circuit will be closed, the magnet 12 energized, and thetransmitter Y released. The revolution of this transmitter first breaksthe contact between 14. and 13. As we have be- 5 fore seen, the circuitof releasing-magnet 12 passes through these points. Hence if thethermostat first operates the transmitter X cannot be released by magnet12 until the arm 13' comes to rest in contact with spring 20,

when the circuit oft he releasing-magnet will be re-established. The arm13 next makes contact with spring 21, closing the following circuit:spring 21, wire 27, bell 2S, magnet 20, battery 30, wire 81, to theframe of the trans- 5 5 mitter, and to arm 13'. This circuit energizesmagnet 29 and releases the cseapcment of an automatic transmitter, whichsends an alarm and station-number over wires 17", 35, and 31 to thefire-department or engine-house in 50 the well-known manner. Thelast-mentioned wires correspond, respectively, to wires 17', 35, and3lthat is, they connect with corresponding parts of a receiver orregister at the tiredepartment. During the revolution of wheel 15, 17makes contact with the projecting teeth, closing a circuit four times.This circuit may be traced as follows: frame of the transmitter, wire3], battery 30, magnet of the signal receiver or register, and wire 17to spring 17. This circuit is indicated by triangular arrow -heads. Themagnet 32, by means of its armature and propelling-pawl, turns thetype-wheel four spaces, after which the pin 1.) comes in contact withspring 18, which closes the following circuit: frame of the transmitter,wire 31, battery 30, mag net 3ft, which controls the printing-platen ofthe receiver or register in a well-known manner, and wire 35 to spring18.

Let it now be supposed that owing to an accident the circuit-controllerat the sprinkler were first operated. As before described, thetransmitter X would be released by magnet 12. At the same time the dropof the annuneiator or electro-magnetic circuit'closer 11 would fall,closing the circuit leading from spring 22, for a purpose which willsoon appear. As arm 13 revolves it first leaves spring ll, opening thecircuit of releasing-magnet 12, so that transmitter Y cannot then bereleased unlil arm 13 comes to rest against sprin 20, when the c rcuitwill be re-established, and this preferably occurs at. the close ofthree revolutions of wheel 15. By giving wheels 15 and 15 a differentnumber of revolutions the recorder will indicate which transmitteroperated, or, it' both, the order in which they operated. During eachrevolution of wheel 15 the spring 17 makes and breaks the circuit whichleads to magnet :32 four times, thus moving the type-wheel four spaces.Then pin 19 comes in contact with spring 18 and closes a circuit throughthe printingmagnet 34, thus recording the number of the station orsprinkler which has become disarranged.

The fact that the circuit-controller at the sprinkler operates firstindicates that it is due to some accidental causesuch as a blow, or ayielding of the fusible link due to too great pressure, rust, or somesimilar ca use -since, as before stated, the thermostats are adj ustedto operate at lower degree of heat than the sprinklers. Itis thereforedesirable to shut oif the water, so that the structure need not beunnecessarily flooded, and means for accomplishing this will now bedescribed. In the water-pipe is placed a normally-open valve, the stemof which is shown at 23o. 1rojecting from the valve-stem is an armcarrying at its end a weight w.

36' is a catch holding the lever in such position as to maintain thevalve open. Adjacent to the catch, on. which is an armature, is a magnet37. The circuit through this magnet is indicated by the double-headedarrows, and may be traced as follows: beginning at battery 10 it passesthrough magnet 11, magnet 12, to the transmitter Y, arm 13, spring 22,and ann unciator-drop, which is now down in the position indicated bythe dotted line, to the lower contact of the switch 38, on which theswitch-arm is placed during the nigh tfor example, when it is desired toautomatically operate the valvethence to magnet 37 and to the other poleof the battery. The closure of this circuit attracts 36, allowing theweight w to descend, closing the valve. Any other suitablevalve-controller may be substituted for the one just described. Duringthe day the switch referred to is preferably moved from the lowercontact to an open position. Should the sprinkler circuit-controllergive way, an attendant might close the valve manually by turning theswitch onto the upper contact, when the circuit would be battery 10 tosaid upper contact, through the switch to the magnet, and back to theother pole of the battery.

It will be clear that should the thermostatic circuit-controller firstoperate it would not be desirable to close the valve and thus shut offthe water, since the operation of a thermostat presumably indicates thepresence of fire, and the water-pressure should remain undisturbed. Toprovide for this is the object of spring 22, before described, sincewhen the transmitter Y is released by operation of the thermostat thecircuit which has been described for automatically closing the valve isopened at said spring 22, and this renders it impossible for thevalve-controller to operate, when on a further rise in temperature theapparatus at the right is released by the giving way of the sprinkler.

Although the operation of the system and apparatus has been indicated bythe foregoing description, it will now be briefly recapitulated. Thethermostatic circuit-controllers in case of fire would be closed,releasing tran smitter Y and recording the number of the station bymeans of the register in which are the operating-magnets 32 34. It maybehere remarked that a time-register such as described in my application,Serial No. 337,424, filed January 20, 1890, is preferred, althoughevidently any other suitable register may be employed. At the sametimedetent-magnet 29 releases the repeater and transmits the alarm tothe fire department. On the receipt of an alarm the attendant, if athand, would of course immediately proceed to the locality of the theand, if possible, extinguish it before the operation of the sprinkler;but if no such attendant were present and the fire continued thesprinkler would give way, and the Water rushing out of the pipe wouldextinguish the fire, at the same time opening the circuit ofrelay-magnet 8, already described.

The operation of transmitter Y indicates the operation of thethermostatic circuit-controller only. The operation of transmitter Y,followed by that of transmitter X, indicates the operation of thethermostatic circuit-controller and of the sprinkler, both presumablydue in this case to fire. The operation of transmitter X only indicatesa disarrangement of the sprinkler, presumably due to accident.

It will be evident that the circuit-controllers in circuit with the twodetent-magnets, as

above described, are automatic and of differ ent character; but it isnot essential that they be of different character, since the duplextransmitter would operate in the same manner if both were controlled bylike circu tcontrollers but operated separately or by different causes.

I do notwish to conline myself to the exact arrangement of circuits andapparatus wh ch I have described, since these may be var ed to aconsiderable extent without departing from my invention.

Having thus described my invention, what I claim is 1.,In a fire alarmand extinguishing system, the combination of a signal-receiver, a duplextransmitter connected therewith, a fire-alarm circuit containingathermostat for controlling one section of said transmitter, anindependent circuit from a second section of said transmitter to anautomatic sprinkler, a circuitcontroller at the sprinkler independent ofthe fire-alarm circuit for controlling said second section of thetransmitter, and a non-interference device for the two sections of thetransmitter, substantially as described.
